Daubert Chemical’s Tectyl 3335 coating is designed to be applied with little cool-down to parts after an e-coating bake stage and to fully cure in extreme (sub-zero) temperatures.
According to the company, the coating was developed for a manufacturer of transportation industry service bodies that had been experiencing excessive undercoating failures. The company used an e-coating primer process for rust resistance, then applied an undercoating to protect the underside of the body from chipping and abrasion. The coated products had to be stored outdoors almost immediately after the undercoating stage, resulting in undercoating adhesion failures.
Daubert says it developed Tectyl 3335 to meet these requirements, and since then there have been no coating failures or refurbishing. In addition to producing the coating, the company also developed a delivery system and a product monitoring process to ensure quality over time.
